of the lever contacting with theflange I5. To j the arm 65'is pivoted at 98 a link ,9I having in its; extremity a slot 92, through which protrudes the for performing certain vital functions in connection with the making of the pizzas, as will be hereinafter seen, andover the remaining seven regions there is located an oven 41, as illustrated. in Figs. 1, 2. Said oven is arcuate about the central shaft I! and comprises a baking chamber 48, a gas flame supplying burner 49, a gap 50 for transit of the shafts 43 therethrough, and posts 5| for supporting the oven, the chamber 48 thereby accommodating the trays 45. Thus, three of the trays 45 are at all times situated in the regions a, b, c, performing resting intervals when registering with the radial lines r of the regions and segmental revolutionary movements between the said lines, while the remaining six' trays are accommodated within the oven 41.

The motorshaft 5 carries a worm 52 meshing with a wheel 53 keyed upon shaft I8 which carries at its upper end a friction cone pulley 54, which is thus continually driven and the function of which will be hereinafter described.

Over the radial line 1" in region a, Fig. 1, is located a pizza loading and preparing device and mechanism 55, Fig. 2, which includes a bracket 56 registering with said line and secured by a hub 5'! to the stationary shaft I1, and the terminal of said bracket is provided with a hub 58 in which is vertically splined a tube 59 carrying a stop flange GI] at the upper extremity thereof and a plate 6| at its lower end. To an ear-piece 62 secured to shaft 1'? as shown is fulcrumed at 33 an arcuate lever 64 having a'handle 65'at the extremity thereof, an arm 36, a slot 31 through which protrudes a pin 38 projecting from the tube 59, and a pawl 59 which is maintained in suspension therefrom by a pivot "I8, the lever 64 being normally maintained in theelevated state illustrated by a spring H secured thereto and to the bracket-56 as shown.

The gear 35 is mounted rotatably about the shaft 38 and provided with a clutching'member I2 having a cammed notch I3 in which normally lodges a pin 14 projecting from said shaft, by

which means the rotation of the gear 35 is'n0r-,

mally transmitted to the shaft 36, which can be slid through saidgear in a direction toward the Said shaft carries a flange I5, between which and the revolvable ring 32 is located,

pulley 54.

a spring 'lficurled about the shaft 35 and secured-to both said flange and the ring, said spring normally drawing the flange toward the ring and thereby maintaining the pin I4 interlocked with the member 72 and clutching the shaft 35 to the gear 35. The terminal of shaft 36 carries a I cone friction pulley TI, which is cooperative with the pulley 54 but normally out of contact there- '1 with, as shown, and said shaft is slidable toward and away from the pulley 54 through its bearings in the arm I8, .and ring 32, impeded in the latter direction by its clutching with the gear 35.

The shaft Il carries a bracket "I8 secured therei to by a hub I9and provided with a projection to which is fulcrumed at 8I a lever 82, one end To'the, opposite extremity of lever 82 is pivoted at 84 a link 85, which is in turn pivoted at B8 to a lever 8! fulcrumed at 88 to the bracket .78, an arm 89 pivoting pin 93 of a lever 94 fulcrumed at 95 to the bracket 18 and in turn pivoted at 96 to a pawl 97. Said pawl is provided with a slot 98, through whichprotrudes a pivoting pin 99 projecting from the bracket 18, and its terminal I80 is toothed and formed to mesh with the worm 40,

though normally maintained out of contact therewith, as illustrated. The lever 94 is also pivoted at 96 to a link IIII which is in turn pivoted at I02 to a hook I83, hinged at I84 to a post I95 projecting from the bracket I8.

In the underside of plate 6i is-formed a spiral the underside oftray I88 are located springy. vbands II'IJ which are interlinked with each other as shown, by means'of headed pins IIDa of one, .passing through slots Ililb of another, whereby these interlinked bands may be contracted to form a narrow collar shown by the dash and dot lines in Fig. 6 and expanded into a large collar, Figs. 6,7. To each band H8 is secured a pin II9c which protrudes through a radial slot 108a in tray I08, which pin is normally drawn toward the shaft IO'Iby asprlng III joinedthereto and I to a pin I881) secured to tray I98. The pins IIIJc have their terminals projecting into the groove I86, whereby rapidrotation of the tray I 08 causes pand saidbands to the position shown, while arrestingrotation of tray I08 draws said .bands to the position, of thedash and dot lines by tension of springs I II The rim I89 is provided 'with pins I991: which engage holes 45a formed in the tray,

the rotation of the latter. 9 When the intermittent revolutionary, travel 45,,when said-rim contacts with said tray, dueto the radial line r of region a, Fig. 1, the pawl GI is directly over the hook I03, and just prior thereto the operative'places a batch II? of prepared pizza dough upon said tray, as indicated in Fig.

2. Thereupon he'swings the lever 64 down-' wardly by its handle 65, which causes thepawl 69-to engage the hook I93 and thereby lockthe' which rotation is transmittedto the tray; 45,.

through'gears -4I, 42 and shaft 43. As during 25 the cam action of said groove to draw said pins and the bands I!!! away fromshaft IIl'Iand ex- 5. of the tray 45 brings its center into registry with e the interval of this operation the tray 45 is in its resting period, the "aforesaid descent and in terlockin g of" the lever 64 brings the rim I38 of inverted-tray.=-I88 closeto the surface of the tray 45 and thereby causes the pins "19a of the former to interengage with the holes 45a of the latter, and the contracted bands H5 to encom- 0..

pass the dough batchlII2. The rapid] subsequent above described rotation of the tray 45. acts centrifugally upon the dough I I 2 and causes it to flatten, while simultaneously the said interengagement similarly rotates the tray I98 and pins IIBC, which beingactuated by the stationary cam I06 expand the interlinked bands III] to their enlarged diameter. In this manner the dough II2 becomes'reduced to a requisite form, diameter, and thickness, indicated by the dash and dot lines II'2a, the above described action and operation of the bands H8, permitting this requisite forming of the dough IIZ by centrifugal force, while operating to properly centre it upon the tray 45 and prevent'lateral deviation thereof. r

1 Simultaneously, the actuated lever arm 66 v draws the-link 9I to swing the lever 94. and

throw the pawl 91 to enmesh its terminal I00 with the worm which causes said terminal to advance rightwardly, as viewed in Fig. 2, and swing, the lever 94 to draw the link I0] and actuate the hook I03 out of engagement .with the pawl 69. Leaf springs saw secured to lever 64 andbea ring upon the'pawl, asshown, normally maintain the pawl 69 in operative condition for locking with and unlocking from the hook I03. This unhooking operation at once restores the, mechanism and its parts to the positions illustrated inFigfZ, the'spring 1I elevating the lever 64 and its dependent parts, and the spring 16 causing the pulley 11 to leave the pulley 54, the shaft 36 tov reclutch. with thegear 35, and the flange 15 to restore the lever 81 with its dependent parts to inoperativecondition, the lever-arm 66 meanwhile actuating its dependent parts to unmeshl the pawl terminal I00 from the worm 40. This operation occurs just prior to the termination of the aforesaid resting period of the tray and restores the tray to its normal rotary condition, whereupon its intermittent revolutionary cycle continues, with the pizza dough rest- .ing thereon in its condition 'I'I2a. I

a .Directly over the centreline' r of the region 22 properly prepared state and is located a bracket II3, secured to thestationa ry shaft, and havingsecured to its terminal I I 4 as; shown, a seasoning device and mechanism H5, Figs. 1 3, and below saidibracket is 10- cated, a bracket, I I6 secured to the same shaft. The mechanism-I I5 is operatedby a vertical shaft I I1 rotatably' mounted in a" bearing ,1 I8 forming part of' a housing II9of the device. Said shaft carries a gear I20 that meshes with a gear I2I keyed upon an oblique shaftI22 rotatably mounted in fabearing I23 fixed to housing l I9 and a bearing I24 forming part'of the bracket H3, and

"the: terminal 'of the shaft ,I22 carries a clutch memberl25. A cooperatingclutch member I26- is splined upon a shaft- I21 rotatable in a bearing- I28, forming part of bracket II6, and carrying'a gear I29 that meshes witha cam tooth I30 forming part of the'rapidly rotating cone pulley 54. The clutch memberl26 is rotatable in a collar I3I from which a pin I32 protrudes throughfa slot I33 of a lever I34 fu1crumed at I35 to the bracket II6, and axlink I36 pivoted at I31 to said lever is provided with a slot I39 through which protrudes a pin I39 of a pawl. I40 pivoted at I4 I to the terminal of the bracket I I6. A pin I42 of said pawl:protrudesthrough a slot I43 of a link I44 which is inturn'pivoted at I45 to a plate I46 that is-slidably mounted'upon the I bracket II6-in the manner shown,by means of a-projection-IM of I the bracket passing through a slot I48 of the plate, and the latter is-provided with a-cain- I49 configurated as indicated in Fig. l.

Aspring I50 joined to pivot I45 and lever I34 holds the latter in contact with the plate 146 as shown, anda spring I5I joined to the pin I39 and bracket II6 maintains the pawl I40 in the position illustrated. I.

' The operating shaft II 1 of the seasoning device and mechanism II5, Figs. 1, 3, 5, carriesya gear I52 that meshes witha gear I53 provided over its area with a series ofgrater teeth I54 and intervening openings I55, thegear- I53 being rotatably mounted in a framing I56 of housing II9 as shown, and upon the teeth I54 rests a;

brick'of hard cheese I51, held within av compartment I58 of said housin Wherebythe rotation of thegear I53 causes'its teeth I54 to grate the cheese I51 and. sift such gratings downwardly throughthe openings I55. I The shaft II1 carries a helical gear I59 that meshes, with a pair of gears I60, Figs. 1, 5, each of which is keyed on a rotatable shaft I6I carrying a pair of pulleys-I62. Over shafts I6I are idler rotatable shafts I63 carrying cooperating pulleys I64, and overeach set of the cooperating pulleys I62, I64 is drawn a wirescreen belting I.65, between which is frictionally held a block of soft, cheese I66,-as illustrated in Fig. 1, whereby the continually moving belts I65 impart yieldable downward movement to the cheese block I 66. Underneath's'aid cheese block is located awheel- I61, the spokes I68 of which constitute knife blades I69joined to ahub I10 keyed upon shaft I I I, whereby as the rotating blades I 69 strike the downwardly moving cheese block I66 they continually slice 01f segments thereof, which slicings drop out'downwardly. 1 Int-he housing II9 are built in tanksI1I containing tomato fluid I12, Fig. 3, which tanks are joined by. a common conduit I13, Fig. 1, and one of said tanks is provided with an orifice I14 normally closed by a cap I15 having a lever-arm I16 fulcrumed at I11 to the housing H9. The cap I15 is normally held closed by a spring I18 secured to the housing, and a cam I 19 forming part ofthe gear I50 strikes the terminal of arm The housing H9 also carries a tank I of olive 911, Fig. 1, from whicha, tube I0! leads directly into the orifice I14, Fig. 3, whereby as the tomato.

fluid leaves said orifice it is admixed withfithe olive oil. The tanks I-1I, I80 are preferably surrounded by chambered jacketings I82 which contain cool water constantly circulated there-. through by pipe lines I83 joined thereto and lead ing to a service source.

' When the intermittent revolutionary travelof the tray 45 brings its centre into registry with the-radial line 1". of region l), Fig. l, it'cornes to a resting period with its axis and that o'fits rotatable shaft directly in alignment with the operating shaft N1 of the'seasoning device II5. As the tray approaches this position its fiange 15 held in place" by its s'trong spring 16 strikes, the cam I49 and thereby shifts it toward the right as viewed in the drawing, and its plate I46 then sli'des accordingly and actuates the lever I34 to slide the clutch member I26 upwardly. This clutches the members I26, I25 and the shafts I21, I22, and power is thereupon trans-. mitted from pulley 54 by means of cam tooth I30 and gear I29, through said shafts, andgears I2I, I20, to the operating shaft II! of the seasoning device II5. The tray 45 being mean while in continued rotation, the shaft Ill operates the said device in the above described man ner to perform all of its functions of depositing seasoning layers in uniformity, of cheeses I51, I66, tomato fluid I12, and olive oil from tank I80 admixed with said fluid, upon the face of toothed terminal I 84 to enmesh' with the worm 40, which causes-saidterminal to advance rightwardly, as viewedin the drawing, and swing said I pawl about its pivot I4I. Upon approach of the pawl terminal "in to the end'of its stroke the pawl lever: I40 draws the link I 36 and actuates the lever I34 to unclutch the members I26, I25,

the parts depending therefrom to the inopera tive positions illustrated in the drawings, the

spring I5I restoring the pawl terminal I84 to its elevated state shown, as said terminal departs from the Worm 40 at commencement of the revolutionary travel of the tray 45. This operation being completed and the pizza 46 havinghad the seasonings fully performed thereon it is carried further bythe revolutionary travel of the tray out of the region I) and into the arcuate oven 41, Fig. 1, wherein it becomes fully baked, until it emerges from the opposite exit 185 into the region 0.

In the region 0 and astride its centre line 1 is located a sector-shaped, shovel-like blade I86, Figs. 1, 4, which blade lies in the plane of the surface of the tray 45. Said blade isheld by 'a hinge I81 in turn held by a plate I88 secured to a post I89 mounted on a bracket i9!) projecting from the machine frame, 2, and to'said hinge is secured a lever I BI that projects downwardly as shown in Fig. 4. Near the lever I9 is situated a horizontal lever I92 pivoted at I93 to a post I94 mounted upon the bracket I90.

Whenthe emerging tray 45 leaves the oven 41, Fig, 1, and arrives at its resting position in registry withthe radial centre line r of region 0,

, v the blade I86 acting knife-like and shovel-like tion.

becomes interposed between the completely baked Pizza 46 and the tray 45, as illustrated in Fig. 4. Upon commencement of the revolutionary movement of the tray 45, its shaft 43 strikes the lever lfilwhich in turn actuates the lever I9I, causing the latter to tilt the blade I86 to the positionshown by the dot and dash lines, Fig. 4, which blade thereby elevates the pizza and conveys it onto the sloping table I95 toward a lever table, not shown, ready for, service and consumpposition, which in turn restores its above actuating parts I9I, I 92 to normal position. I

. It will be evident that in the continuous operaition of this machine, all that'is required by its 1 downward of the lever 84 toinitiate the preparation and centrifugal action of the dough'to the pizza form IIZa, this preparation as well as all the seasonings, baking, and discharging of the pizzas being performed entirely automatically.

Variations may be resorted to within the scope of theinvention, and portions of the improvements may be used without others.
